# 454 CMR: DEPARTMENT OF LABOR STANDARDS 28.11: continued (5) Special Procedures for the Removal or Repair of Asbestos-containing Gypsum Board/Joint Compound Systems as Operations and Maintenance Work. (a) Where removal of sections of gypsum board is required, said sections must be removed intact to the greatest extent feasible. (b) Where gypsum board/joint compound systems must be cut to allow removal or refitting of sections, only the minimum number of cuts necessary to accomplish said removal or refitting must be permitted. (c) Manually operated tools or power tools fitted with HEPA-filtered vacuum attachments must be used for the cutting or resurfacing of asbestos-containing gypsum board/joint compound systems. (d) Where manually operated tools are used for the cutting or resurfacing of gypsum board/joint compound systems, the area being cut must be continually misted with amended water during the cutting operation. (e) Dry sanding of asbestos-containing wallboard/joint compound systems during refinishing operations must not be allowed; only wet sanding is permitted. (f) Where holes of ½" or less in diameter are to be drilled through asbestos gypsum board/joint compound systems, the area encompassing the hole must be covered with a sufficient quantity of shaving foam, or other suitable engineering control, to catch the generated chips and dust. Where holes of greater than ½" are to be drilled, the area being drilled must be continually misted with Amended Water during the drilling operation. ## 28.12 Special Procedures for the Removal of Asbestos Roofing and Siding Materials (1) Requirements for Asphaltic Shingles and Felts.

TENNIS SIGILL THE COMMONWEALTH OF MASSACHUSETTS EXECUTIVE OFFICE OF LABOR AND WORKFORCE DEVELOPMENT SSACH PUBLIC DEPARTMENT OF LABOR STANDARDS # CUT-OFF SAW TOOLBOX TALK Employees who use cut-off saws must be trained to operate the saw safely. Review the Owner's Manual for each model saw that is used. This Toolbox Safety Talk can help review important safety tips. ## Work Practices Review the Owner's Manual for each model cut-off saw you use. ## Inspect each saw before use: • Blade not cracked, chipped, or warped. • Use the correct blade for material and conditions being cut. • Match saw RPM with blade RPM. • Machine guards (belt and blade guards) are secure and adjusted. • Verify throttle and stop switch are working. • Fuel added when saw is cold. ## Prevent Kick-back: • Always keep two hands on the saw. Never operate with one hand. • Never cut above shoulder height. • Do not bend over the blade when cutting. • Support the material being cut to prevent pinching or binding of the wheel. • Do not grind or bevel on the side of the wheel. • Release pressure on the cut-off saw as you reach the end of the cut. • Review owner's manual to understand directional forces on the wheel. • Position your body to keep clear of the wheel and reactive forces. ## Work Safely: • Start saw when resting on ground. Do not "drop start" cut-off saws. • Wet cut when feasible to reduce dust and reduce energy of reactive forces on the wheel. • During transport, do not roll the blade wheel on the ground. • This can damage the wheel and cause shattering during use.

# 454 CMR: DEPARTMENT OF LABOR STANDARDS 28.13: continued C. Dispose of all debris, filters, mop heads, and cloths in sealed, leak-tight containers. 2. Additional Cleaning. The licensed management planner must make a written recommendation to the local education agency whether additional cleaning is needed, and if so, the methods and frequency of such cleaning. (c) Operations and Maintenance Activities. The local education agency must ensure that the procedures described in 454 CMR 28.12(7)(c)1. through 6. to protect building occupants must be followed for any operations and maintenance activities disturbing friable ACM. 1. Restrict entry into the area by persons other than those necessary to perform the maintenance project, either by physically isolating the area or by scheduling. 2. Post signs to prevent entry by unauthorized persons. 3. Shut off or temporarily modify the air-handling system and restrict other sources of air movement. 4. Use work practices or other controls, such as: wet methods, protective clothing, HEPA-vacuums, mini-enclosures or glove bags, as necessary to inhibit the spread of any released fibers. 5. Clean all fixtures or other components in the immediate work area. 6. Place the asbestos debris and other cleaning materials in a sealed, leak-tight container. (d) Maintenance Activities Other than Small Scale Short Duration Ones. The response action for any maintenance activities disturbing friable ACM, other than small scale short durations, must be designed by persons licensed to design response actions and conducted by persons licensed to conduct response actions. (e) Fiber Release Episodes. 1. Minor fiber release episode. The local education agency must ensure that the procedures described below are followed in the event of a minor fiber release episode (i.e., the falling or dislodging of three square or linear feet or less of friable ACM). a. Thoroughly saturate the debris using wet methods; b. Cle…

# Injuries Are Not Accidents: Construction Will Be Safe When It's Designed to Be Safe (cont.) ## Need for an occupational safety and health management systems approach (cont.) construction safety and health management systems (see sidebar, A success story). ## Sustaining the Construction Hazard Prevention through Design (CHPTD) movement In 2007, NIOSH established a national initiative called Prevention through Design (PtD).85 In all business deci- sions, the PtD approach emphasizes the importance of designing out, or at least minimizing, occupational haz- ards early in the design stage to prevent occupational in- juries and illnesses. The first step for the PtD launch was the 2007 National Workshop, at which stakeholders from eight sectors including construction-convened to formulate the PtD strategy. 85 Construction Hazard Pre- vention through Design (CHPtD) is a procedure in which construction engineers and architects consider the safety of construction workers as they design a facility.86 CHPTD has been recognized and implemented inter- nationally as a feasible method to reduce occupational hazards in construction-in particular in the United Construction Hazard Prevention through Design (CHP+D) is a procedure in which construction engineers and architects consider the safety of construction workers as they design a facility. Kingdom (UK) and Australia. 87 In 1995, the UK passed a law requiring architects and construction engineers to incorporate CHPtD when designing facilities.86 In contrast, in the United States, many professional organizations were not aware of the NIOSH PtD initiative in 2007. In all countries, there seem to be similar challenges in implementing CHPtD, such as designers' lack of safety expertise and additional costs, 86 but in the United States. ## A success story: One corporation's construction safety and health management system84 s a result of a partnership between AMEC Construction Management, Inc., and OSHA-a partnership A that …
